Claims. (Cl. 214-1) This invention relates to jacks and it is moreparticularly concerned with jacks for use in lifting and orienting heavyunits and parts involved in the repairing of motor vehicles such astransmissions, differentials, etc.

The general object of the invention is the provision or" an improvedform of jack for the purpose indicated comprising a novel combination ofelements to form a simple, effective and rugged device.

A specific object of the invention is the provision of such a novelarrangement of elements that provides a portable, yet firm, support forheavy loads and controllable movement in various directions for the loadwhile so supported.

Another object of the invention is the use of a combination of elementsthat can be easily assembled and which are not likely to get out ofworking order during long periods of use.

These objects and still further objects and advantages of the inventionwill appear more fully from the following description consideredtogether with the accompanying drawing.

In the drawing:

FIG. 1 is a front elevational view of an embodiment of the invention.

FIG. 2 is a longitudinal sectional view of the lower portion of theembodiment.

FIG. 3 is a cross-sectional view along the line 33 of FIG. 2 on a largerscale.

FIG. 4 is an enlarged view of the upper portion of FIG. 1.

FIG. 5 is a view similar to FIG. 4 showing the tray member in a tiltedposition.

FIG. 6 is a side elevational view of the portion shown in FIG. 4.

FIG. 7 is a sectional view along the line 7-7 of FIG. 4.

FIG. 8 is a sectional view along the line 88 of FIG. 4.

Referring to the drawing with more particularity the embodiment of theinvention illustrated therein comprises a base 11 of a generally squareshape mounted on casters 12.

A hollow post 13 is secured to the base 11 by welds 14 to form a rigidconnection with the frame. The post 13 is further secured in place bydiagonal struts 15 Welded in place between the base frame and the post.

One side of the post 13 is provided with a longitudinal opening 16through which projects the lifting arm 17 of a conventional mechanicaljack 18 of the rack and pawl type. The rack element 19 of the jack ismounted in a vertical position adjacent the opening 16 and is attachedby welds 20 at the bottom to the base 11 and by welds 21 to a spacer bar22 at the top of the post just above the opening 16.

To the lifting arm 17 there is secured by welding a socket 23 alignedwith the longitudinal axis of the post 13 for the purpose of removablyreceiving and rotatably supporting the lower end of a shaft 24. Theshaft normally projects upwardly through the upper end of the post. Aguide collar 25 is secured to the upper end of the post to slidablyengage and laterally support the shaft.

3,185,318 Patented May 25, 1965 To the top of the shaft 24 there isrigidly secured by welding or otherwise, a horizontal plate 26 formingwith angle bars 30 and 31 a platform. The angle bars are welded toopposite sides of the plate. A tray 27 overlies the platform and istiltably supported on it at the rear with brackets '28 hinged by meansof a pin bolt 29 to the angle bars 30 and 31. The front of the tray issupported by a vertical lead screw 32 threadedly engaging a boss 32Asecured to the front of the bars 30 and 31. The upper end 33 of thescrew 32 passes through an aperture 34 of a yoke 35 secured to thebottom of the tray. Flanges 36 and 37 are secured to the screw on eitherside of the aperture. The lower end of the lead screw is provided with acrank handle 38 by means of which it can be rotated manually for thepurpose of tilting the tray.

A strap clamp 39 is attached to the top of the tray for releasablysecuring to it an article carried thereby, such as, a transmission,differential, etc. The clamp includes a clamping bolt 40 on one sidewith a wing nut 41 to adjust pressure of the strap against the part tobe handled. The other end is provided with an aperture 42 which can bequickly engaged and disengaged with 'a hook 43 on the other side of thetray.

The device as a portable unit can be moved into any desired or necessaryposition for removing or replacing, for example, a transmission ordifferential, from a motor vehicle or other such machinery by virtue ofthe ability of the device to provide horizontal movement with thecasters in all directions, vertical movement with the lifting jack,rotatable movement by virtue of the socket between the lifting arm andthe shaft, and the tilting movement furnished by the mounting of thetray :27 on the plate 26.

Having thus described my invention, I claim:

1. The combination comprising a hollow post, portable means supportingthe post in a vertical position, said post having a longitudinal openslot on one side, a tray member above the post, a support memberextending through the slot from the exterior of the post, means formoving the support member along the slot, means laterally supported bythe post for rotatably connecting the tray member to the support memberand means for selectively tilting the tray member and holding it intilted positions relative to the post.

2. The combination as defined by claim 1 and a clamp carried by the trayfor releasably securing to it articles of different sizes and shapes.

3. A jack device comprising a hollow post, means supporting the post ina vertical position for horizontal movement on a horizontal surface,said post having a longitudinal open slot on one side, a shaft coaxiallydisposed in the post, a socket within the post for receiving the lowerend of the shaft, a collar at the upper end of the post for slidablyengaging and laterally supporting the shaft, means connected to thesocket through the slot for raising and lifting the socket on theinterior of the post, a normally horizontal tray member carried by therod on the exterior of the post, and means for tilting the tray memberrelative to the shaft.

4. A jack device as defined by claim 3 in which the means connected tothe socket comprises a vertical rack, a horizontal arm slidably mountedon the rack and means for vertically moving the arm along the rack andfor holding it in selected positions thereon.

5. A jack device comprising a rigid base member, casters attached to thebase member for supporting and translating it on a horizontal surface, ahollow post secured to the base member, said hollow postrhaving alongitudinal opening on one side, an arm disposed through the opening,means for moving the arm vertically and for rigidly supporting it atselected positions relative to the post, a'socket carried by the armfor'movement therewith along'the longitudinal. axis of the post, avertical.

shaft having'its lower end removably seated in, and I0- tatable relativeto said socket, said shaft extending upardly through the upper :end'ofthe posts, a collar secured to the upper end of the post in slidable,contact with the shaft forsupportingit laterally, a horizontal platformrigidly secured to the top of the shaft, a' tray carried by theplatform, said tray being hinged to the platform at one end and a leadscrew between the, other end of the tray and the platform for adjustingthe angular portion of the tray relative to the platform and holding itin the adjusted position.
